I use both the TCON 14B and WCON 08B. This last Sunday I went to a boat show and took my trusty FZ20 with the WCON 08B attached to the Phayee adapter for the specific purpose of shooting boat interiors. Here are three pics with the 8B shot on"P" mode and no flash. I don't see anything that resembles your problem. I didn't even remove the UV filter, just screwed the WCON 08B onto it. Is it possible that you got a defective lens? I shot about 80 pics with no problem. The WCON 08B takes your FZ20 from 35mm to 28mm, not a big change, but it sure helps in cramped quarters.

Hey, I'm sure there are other members here that have used the Oly wcon-08b [edit, sorry] with the fz-20. I just got mine and I'm connecting it to the fz20 with the pemaraal 62mm adaptor. I have noticed that in certain pictures, the center is in focus but there is an outter ring of items out of focus. I'm having a hard time figuring out the zoom range that is optimum for using this lens. Any input is welcome.

Also, I guess I was expecting more but I didn't notice a dramatic change as a result of this lens. What situations would be most appropriate to exploit the capabilities of this lens? I really got it for snapshots at parties to get more into each picture which is why I need to figure out safe zoom ranges but what other cool things has everyone done using this lens?

I also have the Nikon 6t and was blown away by the capabilities of that lens, I guess the impact of the Oly isn't as dramatic. I'm also planning on picking up the Oly tcon-14b soon.

You should not be zooming the WCON08B or any wide-angle. These shots should be done at 1X. The TCON14B should be used from 8X and up for maximum effect.
